WASHING. APPARATUS;

Specification of Letters Patent.

Paten-ted Aug. 9, 19.10;

Appleationled Mayf18, 1910. Serial No. 561,942.

To all whom. fit: may concern:

Be it known that I, FREDRICH` STooKEn, a citizen of the United States ofAinerica, residing at Highland, in the county of Madison and State of Illinois, have invented certain new and usefulImprovements in Washing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to apparatuses for use in washing sand and other materials, the apparatus` forming the subject matter of the present invention being of. the type shown in Patent No. 888,766, issued to me May 26., 1908.

The object of my present invention` is to so construct a washing apparatus of the kind referred to as'to provide for the material being washed, it being retained inv the apparatus for a greater or less period, accord ing to whether it requires a large amount of washing action, or a lesser amount of washing action in cleansing'it.

A further object of the present invention is to so construct the flightsin the apparatus asto provide for their performing their offices more efficiently.

Figure I is a vertical longitudinal section throughA Inv apparatus. Fig. II` is a top` or plan view of the apparatus, the drum being partly broken out, and the endframeslbeing shown in horizontal section. Fig. III is an enlarged4 cross section of the drum, the material conducting chutes therein, and: the means for adjusting, these chutes. Fig. IV is a perspective view of one ofthe handles of the chute adjusting means and the keeper member in which said handle is arranged.

In the accompanying drawings z-l desig nates a drum that is revolubly mounted in end frames 2 and for the support of which rollers 3 are preferably provided. Any suitable means may be made use of for revolving said drum, the means shown comprising a sprocket ring 4 encircling the drum at one end, a driving chain 5 in engagement with said sprocket ring, and shafts 6 and 7 connected by gearing 8 through the medium of which power is communicated to said driving chain.

9 designates hanger bars arranged parallel with each other and supported by the end frames 2 of my apparatus. These supporting bars extend longitudinally through the drum `lI andi` at the end.' ofthe drum provided wth a receiving opening for the maf terial to` be washed, the bars serve to support a feed chute or hopper 10. This feed chute is preferably immovably attached to the supportingbars, and there is preferably also immovably attached to saidi supporting bars, adjacent to the feed chute but located within the drum, a chute l1 that` is inclined downwardly andforwardlyufronr the inlet of the drum. At the opposite end of the apparatus, or that provided with` the outlet opening 1l through which the material that has beenwashed is discharged, isa discharge chute 12, immovably attached to` the supporting bars 9 and projectingthrough the outlet opening. There is also preferably a chute 13, located back of the discharge chute 12and which is immovably supported by the bars 9.

14 is a water conveying pipe through which water is deliveredl to the drum 1i at its discharge end toici-rculate fromthis discharge end toward the receiving end of the drum. No invention per se isherein claimed for the parts thus `far specifically described, inasmuch as they correspond: closely to parts in` my previous4 patent, hereinbeforeL mentioned.

15` designates chutes arranged in series throughout; the central. portion of my apparatus withinithe drum` 1 and` which are piv-` otally connected at 16 tofthe parallel hanger bars 9, thereby providing for said chutes being inclined forwardly towards the de livery end of the drum in any desired degree and` adjusted'` either forwardly or backwardly in order that the material deposited therein may, upon riding downwardly in the chutes, be advanced toward the delivery end of the drum more or less quickly as it is picked up by the drum, through the medium of its ights 17 and emptied into the chutes during the forward movementof the material. To provide for the movement of the chutes 15 in alternate series upon their pivots, each alternate pivotally mounted chute has connected to it a shift bar 18 at one side thereof and the intervening chutes having connected to them a shift bar 19 at `the other side thereof. Each of said shift bars is operated through the medium of a handle bar 2O that is pivoted to the shift bar and is provided at its outer end with a handle 21 and in which are notches 22. The

handle bars 20 eXtend through slots 23 in keeper bars 24 supported by the end frames of the apparatus and which preferably also serve as supports for the hanger bars 9.

In the practical use of my apparatus, the pivotally mounted chutes 15 may be all disposed as they are shown in the drawings, so that the'material delivered to them by being picked up by the flights 17 during revolution of the drum 1 will be gradually advanced from one chute to the neXt, as contemplated in my previous Patent No. 888,766, until the material is finally discharged in a clean condition through the discharge chute 12. In washing very dirty material, it is necessary in order that the cleansing action may be perfect to retain the material in the drum of the apparatus for a greater period of time and dump it a greater number of times into the chutes 15 after -it is lifted out of the water in the drum by the flights; and, in such instances, the chutes 15, either all of them or part of them, are swung backwardly toward perpendicular lines passing through their pivots. Thus, for illustration, if the material that is being washed contains a very large per cent. of dirt, the entire number of pivotally mounted chutes 15 are swung back wardly by the actuation of the shift bars 18 and 19 through the medium of the handle bars 20, so that the material as it is emptied into the chutes and descends therein will not approach the discharge end of the drum as rapidly as it would if the chutes were arranged as they are shown in the drawings andV would, therefore, be subjected to a longer washing operation. In the event that it is desired to subject the material to a washingv operation consuming a period of timev greaterxthan that required when the chutesfare arranged as shown in the draw-.1 ings andless than that when all the chutesv are in nearly perpendicular positions one set of chutes will be swunginto neanl-y vertical positions and the other chutes be allowed to relnain in the positionsshown in the drawings. In this event, the material will advance more rapidly upon one set of the chutes 15 than it does upon the other set of chutes.

An important feature in my present apparatus is the construction of the flights 17 in such manner that they will more effectually control the water and the material introduced into the apparatus, with the result of accomplishing more eiiicient washing action upon the material that is being treated. Each of the flights 17 is curved abruptly near the receiving end of the drum 1, as seen at 17a, the curves at the points mentioned bein@ so located as to provide for the material de ivered into the drum at the receiving end being picked up by the iiights in a manner to direct it forwardly from the forward ends of the iights and into the chutes nearest the receiving end of the apparatus, instead of any of such material being permitted to move backwardly along thc liights toward the receiving end of the drum instead of being properly deposited in the chutes that should receive it.

I claim 1. In a washing apparatus, a revoluble drum, hanger bars in said drum, a series of chutes pivoted to said hanger bars, means for swinging a series of said chutes alternating with intervening ones, and a second means for swinging a series of intervening chutes.

2. In a washing apparatus, a revolublc drum, hanger bars in said drum, a seriesof chutes pivoted to said hanger bars, means for swinging a series of said chutes alternating with intervening ones, and a second means for swinging a series of intervening chutes; said means comprising a shift bar having pivoted connection with one series of chutes, and a second shift bar having pivoted connection with the other series of chutes.
